is a specification.

. 6 This invention relates to the type of cardboard or like boxes, inwhich the body can be collapsed into a flat condition by the clas- 4 ingof two of the angles between the sides and the opening out or flatteningof the other two angles, the present invention having for its object theincreased rigidity of such boxes when set up .for use, the improvementsconsisting of the provision of permanently formed pockets at one or bothends of the sides of the box, which pockets are adapted to receiveflanges on the'lid end or ends when the box is in the set up position.

In order that this invention may be clearly understood and readilycarried into practice, reference may be had to the appended explanatorysheet of drawings, upon which 1-- Figure 1 is a view of a box as whenready for use for containing articles.

Fig. 2 is a view of the same box as shown in Fig. 1, but illustrated aswhen partially collapsed.

Fig. 3 is a view of the same box as shown in the previous figures butillustrated as when fully collapsed and folded for transport.

In an embodiment of this invention the four sides of the body A, B, C,and D, are formed of a length of ,material, which material is bent overto form four angles, 6. e. the angle a between A and G, the angle 0between C and D, and the angle 03 between B and D, while the ends of thematerial adj acent the fold which forms the angle 6 between A and B arewire stitched together at a point adjacent such angle. The materialforming the side B may. be separate from the other sides A, C, D, inwhich case the folded over part b of the side B is stitched to the sideD adjacent the angle (Z or the sides A, B, G, D, may be formed of twolengths of material and stitched as before described either at theangles a 03 or b 0 In the aforementioned embodiment the material formingthe one end E of the box is attached to the end of the side 13 at e Iwhile the material forming the other end F of the box is attached to theother end-of the side B, the material being so bent at the junctionsbetween the ends E, F, of the box and the side B that the one end F ofthe box can be bent over in the direction shown by arrow f until itsface lies' flat against the outer face, of the side B, the other end Eof the box being folded over the reverse way in the direction shown byarrow e until the face lies opposite to the outside face of the side D.

The material of the ends E, F, of the boxes is bent over on three sidesto respectively form flanges e e c and f f f and these flanges may be soformed at the angles as to be capable of occupying a flat position whenthe boxes are in their collapsed condition.

The one edge k of each of a pair of strips H of cardboard is stitchedaround the top and bottom edges of the sides of the body, such strips Hbeing continued around the sides A, C, and D,'so as to form pocketsaround eachend of the sides A, and D, into which pockets the flanges onthe lid are inserted when the boxes are made up for use.

, Strips H forming the pockets may be used only at one end of the sidesin which case the flanges of the lid at the other end would merelyembrace the ends of the sides.

For increasing the pocket opening a base strip may be arrangedintermediately between each outer strip H and the face of thesides ofthe body at the point where the strip is stitched to the sides of thebody, but such base strips of cardboard forming the pockets arepreferably not continued around the angles of the sides of the pocket.The outer strip is attached with suflicient fullness at if to form thepocket around the angles when the box is in the extended condition foruse,'the fullness being if necessary adapted to partially fold over whenthe sides are in their collapsed condition.

What T claim is my invention and desire to secure by Letters Patent is Acollapsible box comprising side members flexibly connected together andend members flexibly connected at one side to one of the side members,and provided at the opposite side and at the ends with flanges; thesides of the box other than that to which the end members are attachedbeing provided with strips,'said strips being fastened 0n the Outside,near the edges, to said sides and being otherwise spaced from said sidesto form pockets between said sides and strips for the reception of thesaid flanges of the end members When the box is set up and closed.

In witness whereof I have hereunto set my hand in the presence of twoWitnesses.
